Samuel Polyak, a New Jersey-based mechanic and EV-converter, turned a 2010 Audi S5 into a gorgeous all-wheel-drive German electric sedan. Polyak separated the Tesla drive unit and inverter to make it fit in the Audi’s front engine bay. To retain the Quattro setup, Polyak created a custom gear-reduction.

The sleek S5 is now packed with an estimated 500-hp powertrain. The range is more than 200 miles. If you like what you see, Polyak will do a conversion for you. Details at polykup.com.
